5 OS/2-specific routines for use with Info-ZIP's UnZip 5.1 and later.
6
7 This file contains the OS/2 versions of the file name/attribute/time/etc
8 code. Most or all of the routines which make direct use of OS/2 system
9 calls (i.e., the non-lowercase routines) are Kai Uwe Rommel's. The read-
10 dir() suite was written by Michael Rendell and ported to OS/2 by Kai Uwe;
11 it is in the public domain.
12
13 Contains: GetCountryInfo()
14 GetFileTime()
15 SetFileTime() (TIMESTAMP only)
16 stamp_file() (TIMESTAMP only)
17 Utime2DosDateTime()
18 SetPathAttrTimes()
19 SetEAs()
20 GetLoadPath()
21 opendir()
